A high power density VHSIC power supply
Fifth Annual Proceedings on Applied Power Electronics Conference and Exposition, 1990A regulated 3.3 V, 10 A supply that combines several innovative approaches is described. The power stage is based on the Cuk converter which allows a very effective application of the integrated-magnetics technique: all magnetic elements (input and output filtering inductors, transformer) are combined on a single magnetic core resulting in a very ...

SH3: high code density, low power
IEEE Micro, 1995Hitachi's SH series microprocessors feature 32-bit RISC architecture with a 16-bit, fixed-length instruction set. We describe SH3, a pipelined implementation of the SH architecture with on-chip cache, MMU, and software-programmable power management.

Development on high-power and high power density capacitor charging power supply
2014 17th International Symposium on Electromagnetic Launch Technology, 2014This paper discussed the high-power and the miniaturization technology of capacitor charging power supply. The design and implementation of parallel operating high power density CCPS prototype with "peak current shifting control" was described. The single CCPS prototype output power is 35kW and the whole output power of parallel operating CCPS is 70kW.

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2013
Abstract In the context of new generation rare isotope beam facilities based on high-power heavy-ion accelerators and in-flight separation of the reaction products, the design of the rare isotope production targets is a major challenge. In order to provide high-purity beams for science, high resolution is required in the rare isotope separation. This

Achieving high energy density and high power density with pseudocapacitive materials
Nature Reviews Materials, 2019Batteries and supercapacitors serve as the basis for electrochemical energy-storage devices. Although both rely on electrochemical processes, their charge-storage mechanisms are dissimilar, giving rise to different energy and power densities. Pseudocapacitive materials store charge through battery-like redox reactions but at fast rates comparable to ...

Power MOSFETs Paralleling Operation for High Power High Density Converters
Conference Record of the 2006 IEEE Industry Applications Conference Forty-First IAS Annual Meeting, 2006In high power high density converters, the power MOSFETs can be used in parallel as the main switch to meet the current rating requirement, increase the switching frequency, and reduce the power loss. This paper investigates the possible benefits and problems associated with the power MOSFETs paralleling operation for higher power high frequency ...

High power density thin film resistors
1975 EIC 12th Electrical/Electronics Insulation Conference, 1975Untrimmed Ni-Cr resistors on glazed alumina substrates, hermetically sealed in a dry nitrogen atmosphere, survive and remain stable when subjected to power densities greater 2000 W/in2. Large (>7 × 10−4in 2 ) resistors with standard top-hat trimming fail at less than 1000 W/in2 due to hot spots, however, a change in trim line configuration results in ...

High Power Density Design Methodology
2007 Power Conversion Conference - Nagoya, 2007Power Electronics Research Center (PERC) proposes a novel circuit parameter design concept called "Power Converter Design Platform" for realizing high output power density (OPD) converters. The platform concept enables the exact power loss design by taking the effect of correlations among converter parameters into consideration under high speed ...
